lol, the horizontal impressions are not cuts or attemp at cuts. Like I said this fine cut in on a giant relief imbedded in it at Karnak.
This is the relief or rather the face of an obelisk which I pointed out when I first posted this pic with an image. Notice the giant image. The bit you refer to is the outer framing and artwork of the relief.
The thick line you think is a saw cut is actually part of the artwork, a border and the vertical line that runds with the cut is some sort of spear of fancy border as well.

There is another cut to the side of the same section as though the entire edge was to be removed to shape the obelisk.

Well looks like your Ai cannot destinguish the difference between a clear cut with art work.
